IMPROVEMENT IN CONDUIT-PIPES.

Specification forming part of Letters Patent No. 37,828, dated March 3, 1863.

T0 aZZ whom it may concern:

Be it known that I, W. S. SAMPSON, of New York city, of the county of New York, in the State of New York, have invented a new Method of Constructing Pipes or Tubes for- Water Conduits, Drains, Oisterns, 850.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My present invention relates to a novel method of forming pipes or tubes for water mains, drains, &c., and has for its object a substitute for the iron pipe now employed, in theproduction ofa tubing which shall be vastly cheaper than iron pipe, and which will at the same time be more durable and desirable in every respect.

In another application for Letters Patent filed in the United States Patent Oiiice on the 27th day of October, 1862, I have fully shown and described a new mode of constructing a cylinder for a grain-bin of peculiarly shaped brick, in combination with iron bond-plates and tie-rods.

My present invention consists in a new manufacture of water pipe and conduits, by combining with a cylinder formed of brick and iron, as shown and described in my former application, (hereinbefore referred to,) an impervious lining, so arranged or applied as to cover all the iron-work on the interior of said cylinder, and render it smooth and suitable for the conduction of fluids, substantially as hereinafter fully explained.

To enable those skilled in the art to make and use my present invention, 1 will proceed to describe the same, referring by letters to the accompanying drawings, forming part of this application, and in which-- Figure 1 is a perspective view of a portion ofa line of water-pipe constructed according to my present invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a cross-section at the line 00 a: of Fig. 2, and Fig. 4. is a crosssection at the line a z of Fig. 2.

Similar letters denote the same parts in the diiferent views.

A is the brickwork. B are the iron bondplates, and a and a the external and internal tie-rods O is the composition or cement lining, which entirely covers the internal tie'rods, a,

and the inner edges and lugs of bond-plates B, as clearly illustrated in Figs. 2, 3,. and 4.

The cylinder A is formed of bricks laid in one side and a groove on the other, (or with one side concave and the other, convex,) as shown in red lines at Fig. 2, and the bondplatesB are made with an annular corrugation or tongue and groove to match the annular tongue and groove of the two courses of brick between which said bond-plate B is arranged. The plates B are connected together by rods a and a, arranged inside and outside of the brick-work A, which rods pass through suitable lugs or projections formed on the plates B, and are secured by screw and nut.

It will be understood that acylinder or tube thus formed will have the courses ton gued and grooved together, and also embraced between the plates B, held together by the rods a a; but this mode of constructing the tube of brick tongued and grooved and locked together by the plates B and tie-rods a a is fully set forth in myother application, in which it is made the sub ect-matter ofthe claim, and need not be more particularly described herein.

After forming a tube of brick and iron, as already described, I coat or line the interior of such tube with a suitable impervious cement or composition, as seen at O. This coating or lining is put on in such a manner as to completely and efl'ectually cover all theiron-worlr, the principal object of covering all the ironwork being to perfectly avoid all oxidation of or other chemical effect on the iron by the water or other fluid passed through or held in the tube, and the accomplishment of this end, in all water-conducting pipes, is a great desideratum, as is well known to all those familiar with the subject.

I propose in some instances to cover the exterior of the tube with a suitable coating of cement or composition, as shown at D, Fig. 3; but when my improved pipe is employed for large water-mains it will probably be deemed most expedient to simply cover the pipe over, when laid, with coarse gravel and a coating oi. asphaltum in the manner now known and practiced in rendering vaults, &c'., impervious to water;

It will be understood that the sections of pipe may be made of any desired length, as Well as diameter, and that it can either be manufactured in lengths and the lengths or sections laid and connected together, "or the bricks and iron-work can be manufactured and a continuous tube of any required length laid down. The tube can be lined either as laid or when the sections are manufactured.

It will be seen that by lining the interior of the tube, as shown at O, coveringall the protruding iron-Work of the cylinder, the interior of the tube presents a perfectly smooth surface. This is a great desideratum f r waten mains, and also for'tuloes for drains and ether purposes. 7

"A cylinder constructed after my present ine tian and p ovided w t me abl tQ-e! and other known appurtenanceswill make a most excellent reser 'oir or cistern, and Ipron o m o y n t en for h s. purpose- It s bv ous that m n e q'n s s b e 1 m y qi fi ons nd da t d to. el' q s, riums bes s hese pe ia a to;

and I wish to be protected in the enjoyment of my rights to my said invention in all its different applications or uses.

I am aware that iron pipes have been lined also that cisterns have been made of ordinary brick-work and lined with Portland, Roman, and other cements, which I propose to use also for lining my tubes; but all such modes of construction and combinations are entirely different from my invention.

What I claim as new, and desire to secure by Letters Patent, is-

Forming tubes or cylinders for water-pipes, cisterns, &c., of tongued and grooved or otherwise equivalently shaped bricks and iron bond-plates and tie rodjs, in combination with a composition or cement lining covering the iron-work, substantially as and for the pur: poses hereinbefore set forth.

In testimony whereof I have hereunto set m aml- WM. S. SAMPSON.
